# 1.7 Functional Description

# Processor Support

The M-302 motherboard supports Intel processors in the LGA775 package in a range of 533/800/1066 MHz Front Side Bus (FSB).

Providing high-performance computing and energy-efficiency, the M-302 is designed for Intel® Core™2 Duo, Intel® Pentium® Dual-Core, Intel® Pentium® 4, Intel® Celeron®, and Intel® Celeron® D processors. The M-302 supports dual-core processors containing multiple physical cores and dedicated L2 caches to meet the ever-increasing demands of industrial computing.

# Intel® Q965 Express chipset

The Intel® Q965 Express chipset, featuring the Intel® Q965 graphics memory controller hub (GMCH) and the Intel® ICH8DO I/O controller hub, provides the vital interfaces for the motherboard. The Intel® Q965 comes with the Intel® Graphics Media Accelerator 3000, an integrated graphics engine with enhanced 3D/2D graphics rendering and video capabilities. The GMCH also provides the interface for the processor and system memory.

The Intel® ICH8DO Southbridge is the eighth generation of Intel I/O controller hub that provides key interfaces such as PCI Express®, USB 2.0, and SATA II.

# Dual-channel DDR2 memory

To meet the requirements of memory-intensive applications, the M-302 has a dual-channel memory architecture supporting DDR2 533/667/800 MHz DIMMs. The high-bandwidth memory specification, meets the requirements of the latest 3D graphics, multimedia, and network application, and boosts system performance by eliminating bottlenecks.

# Intel® Graphics Media Accelerator 3000

The Intel® Graphics Media Accelerator (GMA) 3000 revolutionizes integrated graphics with new capabilities that provide significant increase in graphics performance. With support for DirectX 9 hardware acceleration, 333 MHz display clock, and up to 256 MB of video memory, the Intel GMA 3000 provides a cost-effective and high-performance graphics solution. The M-302 comes with the dual-independent display technology, enabling different contents to be displayed on two separate display terminals or a single content stretched across two display devices for expanded workspace.

# Gigabit Ethernet

The M-302 is equipped with the Intel® 82566DM PCI Express controller.

# Serial ATA

Storage is efficient and secure with the Serial ATA interface. Utilizing the Intel® ICH8DO, the M-302 supports up to six Serial ATA devices capable of reading/writing data at up to 3 Gbps. The SATA specification improves chassis airflow via thinner and more flexible cables with lower pin count.

# USB 2.0

The M-302 incorporates the Universal Serial Bus (USB) 2.0 specification that increases peripheral connection speed from 12 Mbps (USB 1.1) to 480 Mbps. USB 2.0 is backward compatible with USB 1.1.

# Hardware monitoring

A built-in, proactive hardware monitoring system in the ASIC monitors the CPU temperature, system fan rotations, and voltage levels to prevent overheating and/or component damage, effect timely failure detection, and ensure stable supply of current for critical motherboard components.

# Watchdog Timer

The watchdog timer (WDT) monitors system operations based on user-defined configurations. The WDT can be programmed for different time-out periods, such as from 1 to 255 seconds or from 1 to 255 minutes. The WDT generates a reset signal, then a reset request, after failure to strobe it within the programmed time period. A register bit may be enabled to indicate if the watchdog timer caused the reset event. The WDT register is cleared during the power-on sequence to enable the operating system to take appropriate action when the watchdog generates a reboot.

# 3 Getting Started

This chapter provides information on how to install components to the M-302 SBC. Specifically, the installation of CPU, memory modules, and operating system are explained.

# 3.1 Installing the CPU

The M-302 Supports the Intel® Core™2 Duo, Intel® Pentium® Dual-Core, Intel® Pentium® 4, Intel® Celeron®, and Intel® Celeron® D processors via the surface mount LGA775 socket (Socket T).

![The image displays a standard safety warning sign. It features a red triangle with a white border containing a white exclamation point. Below the triangle, the word 'WARNING' is printed in black capital letters.](.m-302-50-13062-1010-201-en/98d3d10e4804b7a322dc20f64f912b0a5d2322eb4f54b2eb49683dbd3d6ba3a7.jpg)

Disconnect all power supply to the board before installing a CPU to prevent damaging the board and CPU.

Do not touch socket contacts. Damaging the contacts voids the product warranty. Follow the installation instructions carefully to avoid damaging motherboard components.

# 3.2 System Memory

The M-302 supports up to 8 GB of DDR2 533/667/800 SDRAM in four 240-pin DIMM sockets. See Figure 1-2 on page 11 for DIMM socket locations.

# Memory Configurations

Dual channel configuration is supported by the M-302 as follows:

Channel A: DIMM\_A1 and DIMM\_A2

Channel B: DIMM\_B1 and DIMM\_B2

Unbuffered non-ECC DDR2 DIMMs with capacities of 256 MB, 512 MB, 1 GB and 2GB can be installed into the DIMM sockets as follows:

▶ Memory modules of varying sizes may be installed in Channel A and Channel B. The system maps the total size of the channel with the lowest capacity for dual-channel configuration. Any excess memory from the channel with higher capacity is then mapped for single-channel operation.
▶ Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.
▶ Due to chipset resource allocation, the system may detect less than 4 GB system memory when four 1 GB DDR2 memory modules are installed. This limitation occurs in Windows® XP 32-bit operation system, which does not support Physical Address Extension (PAE).
The M-302 does not support memory modules with 128 Mb chips or double-sided x16 memory modules.

# Memory Module Installation

The DDR2 memory modules are notched to facilitate correct installation in the DIMM sockets.

![The image displays a standard warning sign. It features a maroon triangle with a white border containing a large white exclamation point in the center. Below the triangle, the word 'WARNING' is written in white, uppercase letters.](.m-302-50-13062-1010-201-en/924ad3d71a1a237e60073b05b6a2c761df64ddce7f20958ad9780ad80e743cd9.jpg)

Disconnect all power supply to the board before installing a memory module to prevent damaging the board and memory module.

# To install a memory module:

1. Locate the DIMM slots on the motherboard.
2. Press the socket's retaining clips outward to unlock.

![Black plastic mechanical component with red arrows indicating direction (no text or symbols)](.m-302-50-13062-1010-201-en/c271c1b63035c9a01ab8ae478b1e758577e7f6d8b239fd9dd2bf2bd8b34583a6.jpg)

3. Align the memory module on the socket making sure that the notch matches the break on the socket.

![Notch\n512 MB\n00HJ 833\nBreak](.m-302-50-13062-1010-201-en/a19576d9c90dd187a55f9267c1a502855f05e6dda3f7ca2f71a9d9ed72f55cab.jpg)

4. Insert the module firmly into the slot until the retaining clips snap back inwards and the module is securely seated.
